我正在使用 sqlite 文件从 authorId 中获取 diaryEntriesTeacher,但当我打印变量 authorId 时,它生成了以下对象,其中 authorId 为 nil。
代码:-
func applySelectQuery() {
checkDataBaseFile()
objFMDB = FMDatabase(path: fullPathOfDB)
objFMDB.open()
objFMDB.beginTransaction()
do {
let results = try objFMDB.executeQuery("select * from diaryEntriesTeacher", values: nil)
while results.next() {
let totalCount = results.resultDictionary
let authorId = totalCount?["authorId"]!
print("authorId",authorId)
}
}
catch {
print(error.localizedDescription)
}
print(fullPathOfDB)
self.objFMDB.commit()
self.objFMDB.close()
}
